AMALGAMAI'ING-MACHINE.

SPECIFICATION forming part of Letters Eat-ant No. 694,204, dated. Fe'lo1 -i1a1-y 25, 1902 Application filed' May 20,

To all whom it 1nay;00ncorn.-

Beit known that I, GERARD O. SCOTT, acitizen of the United States, residingat Columbus, in the countyof Franklin and State of Ohio, have invented a certain newan d. useful Improvement in Amalgamating-Machinos/,of which the following is a specification- My invention relates to the improvement of amalga'mating-machines; and the objects of my invention are to provide an improved machine of this class of superior construction and arrangement of parts, to provide improved means for subjecting the incoming ore-pulp to the amalgamating action, to provide improved means whereby an increased copper surface is provided, and produce other improvements the details of construction of which will be more fully pointed out hereinafter. These objects I accomplish in the manner illustrated in the accompanying drawings, in which Figure 1 is a central vertical longitudinal section of my improved amalgamating-machine, and Fig. 2 is a transverse section on line a: w of Fig. 1.

Similar numerals -refer to similar parts throughout the several views.

In carrying out my invention I employ-an external casing 1, which, as indicated in the drawings, is preferably constructed .of upper and lower detachably-connected semicylindrical sections 1 and 1". The case thus formed is provided in its upper portion adjacent to one end with a suitable inlet 2 and at its opposite end with an outlet 3. Within the central portion of the casing is journaled a shaft 4, upon one end of which is mounted a suitable power-wheel 5, the operating belt or cord 6 of which may pass through the inletopening 2. Mounted upon the shaft 4 and carried thereby is a closed drum or cylindrical body 7. Suitably connected with the periphery of the drum 7 and extending throughout the length of the latter are the inner edge portions of the desired number of radially-arranged partitions 8, the latter being formed of Wire-netting or. of suitable open-work. These partitions serve to connect the periphery of the drum 7 with a larger cylinder or casing 9, shown as formed of wire-netting. The radial compartments thus formed between the partitions 8 and between the outer 1901. SerialNo.6l,023. mamas,

surface of the drum 7 and inner surface of thefcasing 9 are adapted to be closed at their ends by suitable open-work or netting, such as is indicated at 10 in Fig. 2. These compartments'are'filled with suitable-sized copper fragments or lumps,'which are indicated at 11. Upon the shaft 4, adjacent to one end thereof and on the outer side of the drum, I provide mixing or agitating arms 12, and upon thepower-wheel 5 I provide suitable forms of laterally-projecting agitating-arms 13.

In constructing the lowersection of the easing 1 I form beneath and about the lower portion thereof a jacket or heating-compartment 14, which is provided with inlet and outlet openings 15 and 16 at opposite ends.

As indicated by the horizontaldotted lines in the lower portion of the casing 1, I provide the lower section of said casing with a body of mercury 17.

In utilizing my invention the ore-pulp enters the casing 1 through the inlet 2 under suitable pressure, and rotary movement is contributed to the shaft 4, drum 7, and the radial copper-containing compartments through rotation of the power wheel 5. The pulp which thus enters the casin g is carried through the copper containing compartments and through the open-work partitions to said compartments,while the copper granules throughrotation of the shaft and drum are carried through the body of mercury in the lower portion of the casing, thus subjecting the copper to the action of the mercury and at the same time subjecting the ore to the separating or amalgamating action of the mercurially-treated copper. In this operation it will be seen that comparatively simple al though effective means are provided for subjecting the ore to the amalgamating action of a comparatively large copper surface and that owing to the employment of the openwork inclosures and the loose or granular character of the copper the passage of the pulp therethrough will not be unduly obstructed. In order to further agitate or min gle the material contained within the casing, I have provided the agitating-arms l2and 13, the former being of such length as to prevent their engaging the body of mercury contained in the casing.

Steam or other suitable heating element IOCI may be introduced into the jacket 14 for the purpose of imparting the desired temperature to the mercury.

Although the copper bodies herein described are shown as solid, it is obvious that in order to reduce the Weight of the same said copper bodies may be formed hollow and of any suitable outline.

Having now fully described my invention,

what I claim, and desire to secureby Letters Patent, is-

1. In an amalgamating-machine, the combination with a substantially horizontallydisposed casing having inlet and outlet openings, a shaft journaled therein and means for imparting motion to said shaft, of a cylindrical body mounted on said shaft and having surrounding separated compartments containing copper in a granular form, said cylindrical body having open-work ends and said casing adapted to contain a body of mercury in the lower portion thereof, substantially as specified.

2. In an amalgamating-machine, the combinationwith a casing having inlet and outlet openings and a shaft journaled in said casing, of a body mounted on said shaft havingradially-arranged compartments formed by open-work partitions, said compartments containing copper in a loose form and said casing adapted to contain a body of mercury in the lower portion thereof, substantially as specified. I

3. 'In ana'malgamating-machine, the combination with a casing having inlet and outlet openings, of a shaft journaled in said casing, a drum carried on said shaft, a casing connecting with and surrounding said drum and having radiallyrarrauged compartments divided by open-Work partitions, a filling of copper Within said compartments, agitatorarms on said power Wheeland shaft and said casing adapted to contain a body of mercury in the lower portion thereof, substantially as specified. v
